Each type may further be divided into external and internal wall. External walls are for enclosing and internal walls are for dividing the space.
Loading bearing walls are designed to carry super-imposed loads transferred through roofs in addition to their own self-weight.
Non-load bearing walls carry their own load only. They generally serve as divide walls or partition walls.
Panel wall is the external non-load bearing wall, commonly related to framed structures.
Partition wall is a thin internal wall which is constructed to divide the space within the building into rooms or areas. It may either be non-load bearing or load bearing.
Party wall is a wall separating adjoining buildings belonging to different owners or occupied by different persons. It may or may not be load-bearing.
Separate wall is a wall separating different occupancies within the same building.
Curtain wall is a self-supporting wall carrying no other vertical loads but subject to lateral loads. It may be laterally supported by vertical or horizontal structural members where necessary.
Cross-wall construction is a particular form of load-bearing wall construction in which all the loads are carried by internal walls, running at right angles to the length of the building.
